2.2.8 Setting the module address

For hydraulic modules or heating circuit modules it is necessary to set the required or‐
der with the module addresses. The first board of a module type should always have
the address 0, so that the standard hydraulic systems set do not have to be subse‐
quently configured. For further module types ascending module addresses (address 1

- 7) are set.
A hydraulic module with address 0 is included in standard delivery. If a second hy‐

draulic module is also installed, address 1 is set.

4.3.1 Heating up

Item Description

1 When the insulated door is opened the status, "Door open", is shown on the display

and the basic display is replaced by the flue gas temperature and the parameter "ID
fan". The parameter is automatically set to "ON" and the ID fan is activated at maxi‐
mum speed.

2 The ID fan can be switched on and off with the arrow keys.

NOTICE! When igniting the paper, it is advisable to turn off the induced draught fan
and to turn it on again afterwards.

▪

Fill the boiler with fuel and ignite it following the boiler operating instructions

3 After closing the insulated door the boiler switches automatically to "Heating up"

status. The Lambdatronic S 3200 activates the induced draught at 100%.

4 When a specific minimum flue gas temperature is reached or when the specified maxi‐

mum heating up time has elapsed, the boiler changes to "Heating" status. The
Lambdatronic S 3200

controls the combustion according to the boiler setpoints that

have been set.

5 If the criteria for "Heating" status are not reached within a specified time, the boiler

switches to "Off" status.

4.3.2 Heating up with automatic ignition

Item Description

1 When the insulated door is opened the status "Door open" is shown on the display

and the basic display is replaced by the flue gas temperature and the parameter "ID
fan". The parameter is automatically set to "ON" and the ID fan is activated at maxi‐
mum speed.

❒

Fill the boiler with fuel

NOTICE! See operating instructions for the S4 Turbo firewood boiler

2 The ID fan can be switched on and off with the arrow keys.

After closing the insulated door the boiler automatically switches to "Preventilation"
status.

To guarantee a safe boiler operating status and to rule out possible ignition by residu‐
al embers due to incomplete cleaning of the combustion chamber, the boiler attempts
to reach "Heating" status within a specified safety time without activating the ignition.
Within this time period, heating up can be carried out manually, to bypass the auto‐
matic ignition.

3 Once this safety time has passed, the boiler remains in “Ignition wait” status until the

time for automatic ignition set in the Ignition menu is reached.

⇨ See "Menu - Ignition" [page 59]

4 The fuel is ignited with the fan-assisted ignition. The boiler must reach the criteria for

“heating” status within a specified time. If the ignition attempt fails, an error is shown
on the display.

Within a specified time the boiler attempts to reach the status Heating

without activating the ignition. Within this time period, heating up can be
carried out manually, to bypass the automatic ignition.

Ignition wait
(with autom. igni‐
tion)

When the safety time has elapsed (operating status preventilation) the
boiler remains in the status "ignition wait" until the time specified in the
ignition menu for the automatic ignition has been reached.

Ignition
(with autom. igni‐
tion)

The fuel is ignited with fan assistance. The boiler attempts to reach the
criteria for heating status within a specified time.

Heating The Lambdatronic S 3200 controls combustion according to the boiler

setpoints.

Slumber Very low power consumption.

When the boiler temperature setpoint is exceeded by a specified value,
the boiler goes to "Slumber" status. The fan stops and the air flaps are
closed to the minimum opening.

If the temperature falls below the boiler temperature setpoint the boiler
goes back to “heating" status.

Door open The insulating door is open and the fan runs at maximum speed.

met, the isolating valve immediately clears the way for boiler loading. The
heating circuit pump starts running as soon as the “Load if tempera-
ture difference between boiler and DHW tank is” criterion
is reached. Once DHW tank loading is complete, the heating circuit pump
will stop, the isolating valve will remain active for a specified period of time
and the heating circuit mixer will close. If time has run out, the heating cir‐
cuit will go back to being supplied on a weather-compensated basis.

NOTE: Parameter only available with heating circuit 1 and generally only
used in conjunction with the unit model of the P1 Pellet pellet boiler!

High temperature requirement be‐
cause of DHW tank loading

NO If this parameter is set to YES, the remote line is operated according to

the set heating curve + overcharge. Whilst the DHW tank is loading, the
remote line is supplied for a short time at a higher temperature, but once
the DHW tank is loaded, it is supplied again according to the heating
curve.

NOTE: Parameters for heating circuit 2 only!

For high temperature requirement
don't look at DHW tank 01

NO If DHW tank 1 is positioned in front of the network mixer, it should not af‐

fect the temperature control of the remote line, therefore this parameter
should be set to YES.

After the 30 days, the heating circuit that has been set operates based on
the set heating times again.

❒

The heating times of the selected heating circuit are automatically set
to 0:00-24:00 and the external temperature heating limit is ignored.

❒ In order that enough heat is always available to the heating circuit, the

boiler and/or storage tank loading times must be set to 0:00-24:00.
When using a firewood boiler, a corresponding heat supply must be
ensured.

“Date and time” method:
Ignition starts at the specified time exactly. If the parameter is set to “daily”
instead of the date, ignition starts every day at the specified time.

“Buffer tank min” method:
The ignition process starts if heat is requested from the storage tank from
the specified time (parameter "Boiler start if difference be-
tween boiler setpoint and top store is larger”). The peri‐
od applies from the specified time until 24:00 h on the specified date. If the
specified time is not subsequently changed and ignition is not disabled,
the store loading criterion applies daily from the specified time.

"Buffer < f.flow” method:
The maximum flow temperature required by the system environment (e.g.
heating circuit) is compared with the current storage tank temperature
from the specified time. If the top storage tank temperature falls below the
maximum flow temperature setpoint, the ignition process starts. The peri‐
od applies from the specified time until 24:00 h on the specified date. If the
specified time is not subsequently changed and ignition is not disabled,
the start criterion applies daily from the specified time.

❒

Open the insulated door

➥ Before starting calibration, the insulated door must be open for at least 3 - 4

minutes so that the probe is warm enough and the boiler is sufficiently ventila‐
ted

For boilers with automatic loading:

❒ Boiler must be switched off

➥ Status "Boiler OFF" or "Standby"

❒ Set "Lambda probe heating" parameter in the "Manual" - "Digital out-

puts" menu to "1"

➥ Heat Lambda probe for at least 2 minutes

Calibrate probe:

❒ Go to parameter "Broadband probe calibration"
❒ Set parameter to "YES" and press the enter key

➥ Automatic calibration of the broadband probe begins
➥ Once calibration is complete the parameter is automatically set to "NO" and the

5.13 PWM / 0 - 10V settings

Description

▪ Normal pump (pump with load-tap changer)

Set when a standard pump a switching valve with RC element is run at the respective output. When using a switching
valve, set the minimum speed of the output to 100%. When a pump is used, it is controlled at the 230V output using
pulse packets.

▪ PDM / field pump

There is a permanent power supply of 230V at the output for the high efficiency pump. The pump is controlled using
pulse duration modulation at the respective PDM output.

▪ PDM / Solar pump

Here again, the pump is controlled by means of pulse duration modulation at the respective PDM output. In this case,
however, the characteristic line is inverted and can only be used for specially marked high efficiency solar pumps.

▪ PDM field Pump+valve

The signal for the field pump is emitted at the PDM output. If the signal exceeds 2%, the 230V output is switched on. If

the signal is below 2% for more than 4 minutes, the output is switched off again.
▪ 0 – 10V / field pump
▪ 0 – 10V / solar pump
▪ 0 – 10V field Pump+valve

The same functions that apply with PDM apply to the parameter values with 0-10V. The only difference is that instead

of pulse duration modulation, a 0-10V signal is used to control the pump.

6 Troubleshooting

The term "fault" is a collective term for warnings, errors and alarms. The boiler reacts
differently to the three types of message:

WARNING In case of warnings the status LED flashes orange and the boiler initially

continues controlled operation.

ERROR In case of errors, the status LED flashes red, the boiler follows shutdown

procedure and remains in operating status "

Off ", until the error is re‐
solved.
After troubleshooting, the boiler switches back to the operating status
"Off".

ALARM An alarm triggers a system emergency stop. The status LED flashes red,

the boiler switches off immediately and the heating circuit controller and
pumps remain active.

6.1 Procedure for fault messages

When a fault occurs:

▪

The status LED flashes red or orange

▪ The display shows all the current fault messages and the warning symbol in the

status line

Procedure for fault messages

Operating Instructions Lambdatronic S 3200 | B0361214_en 83

After pressing the enter key the
fault is acknowledged.
The warning symbol in the status
line shows that the fault is still
pending.

Pressing the info key displays the
fault as info text with the related
fault number.
The warning symbol only
switches off when the fault has
been resolved!

After pressing the enter key an in‐
fo text on the cause of the fault is
displayed. Pressing the enter key
again displays instructions for re‐
solving the fault.

If a fault has various causes or
the cause can be resolved in vari‐
ous ways, you can scroll through
with the navigation keys.
